Leviticus 9:2

1On the eighth day, Moses called Aaron and his sons, and the elders of Israel;

2and he said to Aaron, “Take a calf from the herd for a sin offering, and a ram for a burnt offering, without defect, and offer them before the LORD.

3You shall speak to the children of Israel, saying, ‘Take a male goat for a sin offering; and a calf and a lamb, both a year old, without defect, for a burnt offering;

4and a bull and a ram for peace offerings, to sacrifice before the LORD; and a meal offering mixed with oil: for today the LORD appears to you.’”
